Predxcat estimates and graphs adjusted means or adjusted proportions for
categorical X variables from linear or logistic regression models, and
predxcon does the same for continuous X variables. The survey versions
are called:

svypxcat -- for predxcat
svypxcon -- for predxcon

Also, predxcat and predxcon have been updated to use the current
graphics capabilities, and have new options, including cluster( ) and an
option to save results to a data file.
